Car Air Conditioning Service
Precision Automotive LPG are qualified to handle all of your Automotive Air Conditioner inspections, repair or servicing in Katoomba and the surrounding areas.
These days vehicles are often complex and just like the engine, a car air conditioner has components that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. Your air conditioner system uses refrigerant to extract the excess heat from the air in the interior area of the car then transfer it out of the car, leaving only cooled or 'conditioned' air behind to be redistributed. It is important that the rubber seals are inspected for any signs of leaks or detoriation which may point to a loss of refrigerant.
If this refrigerant starts to leak or evaporate your air con system will begin to deteriorate and have to work harder with a resulting increase in fuel usage. Even new cars can lose approximately 20% of their refrigerant gas within two years of purchase.
To avoid this situation it is strongly recommended that the refrigerant in your Car Air Conditioner is replenished completely within four years of the manufacture date and every two to three years after that.
Having your car's air conditioning serviced once a year means you may assist preventing costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioning system actually saves you money because it means less fuel is being expended.
You should send your car to a qualified workshop such as Precision Automotive LPG regularly to make sure the air conditioning system continues performing in optimum conditon as well as having the mechanics check the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection reportwith every service and are usually able to give you a warning about any items that may need to be renewed in the near future or those that are already worn beyond repair.
Precision Automotive LPG in Katoomba are qualified to conduct air conditioning repairs, services and regas on most makes and models (AU33979).
Air Conditioning FAQ's
A car air conditioner system can be classified into four basic parts - a compressor (Pump driven by the engine,) which compresses and circulates refrigerant gas, a condenser, which behaves similarly to a radiator to remove heat and condense gas to a liquid, the evaporator (a type of heat exchanger) to remove heat from the car and dehumidify refrigerant and an expansion device known as a thermal expansion valve (TXV) or an orifice tube, (dependent on the sort of air-con system used).
A vehicle air conditioning is designed to take the heat from the air inside the vehicle then transfer it outside, leaving only cooled or 'conditioned' air behind to be redistributed. As hot air is passed across the fins of the evaporator the heat is easily absorbed by the refrigerant (in gas form), effectively removing the heat from the air in the car and taking it outside.
The now heated gas is pulled through the compressor where it is further heated (via compression) to a very high temperature. The refrigerant is then literally forced through the condenser, allowing the cooler outside air to quickly extract the heat from the refrigerant as it is condensed to a liquid. The refrigerant then moves through the expansion device (either a TXV or Orifice tube), which regulates the flow of refrigerant going to the evaporator. At this point the refrigerant expands back into a gas form and the entire process begins all over again.
What comprises a car air conditioner service?
A typical air conditioner service may include
Air vent temperature inspection
- Inspect condenser temperature
- Confirm suction line temperature correct
- Adjustments of pulley and drive belt
- Validate correct operation of valves and thermostats
- Check condenser fins are free of dirt or debris
- Inspection of components and hoses
- Evacuation and recharge of refrigerant (where required)
- Check system lines and components for leaks with an electronic leak detector
Why do I need a car air conditioner system service?
Preventing compressor seizure is achieved by checking or changing the oil level in the refrigerant. If the air filters become jammed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to fail to operate altogether. Aside from degrading air conditioner performance, dirty air filters can cause all kinds of health problems too.
Your vehicle air conditioning system ought to be examined once a year for any signs of issues with the seals, hoses and connections to make sure refrigerant is not being lost over time. Regular service of your automotive air conditioner keeps refrigerant at optimum levels meaning the system does not need to work as hard and this in turn protects the system from damage and reduces the amount of fuel you use.
A vehicle air conditioning is designed to take the heat from the air inside the vehicle then transfer it outside, leaving only cooled or 'conditioned' air behind to be redistributed. This is achieved using a special compound called refrigerant, capable of readily absorbing heat as a gas and quickly losing heat as a liquid.
Although it functions in a way like a domestic refrigerator, there are a couple of crucial differences. Seeing how it is mounted on your car, the air conditioning system is subject to a colossal amount of movement and vibration in addition to performing in an outdoor environment.
Being exposed to the mercy of the elements and very diverse operating conditions and being in use intermittently rather than being 'Always On' can cause failure of the seals, hoses and connections. Your automotive air conditioner system must be examined yearly as well as being properly serviced at least every two years to ensure there are no problems or refrigerant loss due to failure or leakage from these points.
Simply by cooling the air in your car under normal running conditions, the filters of the air con get dirty. If the system is run infrequently, seals may dry and crack allowing them to leak and the air conditioning system can lose as much as 15% of its refrigerant in a single year. Even without leaks, the gas in a car air conditioning system will eventually degrade or evaporate over time and should be recharged regularly to keep the air con system in peak running condition
Under Australian law, only qualified mechanics with the appropriate licences are able to service or repair car air conditioning systems, especially where regas (recharging of the refrigerant) is concerned. Strict guidelines and procedures must be adhered to when handling refrigerant, which must always be fully recovered and not allowed to escape into the atmosphere during servicing.
Refrigerant can also pose serious health risks if handled incorrectly. Specialist equipment is also required as the air conditioning system is under extreme pressure and must be pulled into a deep vacuum to remove any moisture, which can seriously damage the system.You can find out more about licensing on the Australian Refrigeration Council (ARC) Website.
The moist environment inside the evaporator core can promote the development of microbes, bacteria and even fungus growth. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. While modern evaporator units tend to be more efficient, the addition of extra fins leads to an increased ability to trap moisture, allowing micro-organism development.
Precision Automotive LPG mechanics will use specialised ultrasonic technology to remove any micro-organisms that may cause bad odours or health issues.Just ask about our MIST service, which will kill any bacteria that may be lurking in your Car’s Air system. These bacteria can cause odours and even make you sick, especially if you have allergies or asthma. A MIST service doesn’t just make your car smell better - it makes it healthier for you and your family.
